DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will be described below withreference to the attached drawings.

The terms “module” and “unit” used to signify components are used hereinto help the understanding of the components and thus they should not beconsidered as having specific meanings or roles. Accordingly, the terms“module” and “unit” may be used interchangeably.

An image display apparatus as set forth herein is an intelligent imagedisplay apparatus equipped with a computer support function in additionto a broadcast reception function, for example. Thus the image displayapparatus may have user-friendly interfaces such as a handwriting inputdevice, a touch screen, or a pointing device. Further, because the imagedisplay apparatus supports wired or wireless Internet, it is capable ofe-mail transmission/reception, Web browsing, banking, gaming, etc. byconnecting to the Internet or a computer. To implement these functions,the image display apparatus may operate based on a standardgeneral-purpose Operating System (OS).

Various applications can be freely added to or deleted from, forexample, a general-purpose OS kernel in the image display apparatusaccording to the present invention. Therefore, the image displayapparatus may perform a number of user-friendly functions. The imagedisplay apparatus may be a network TV, a Hybrid broadcast broadband TV(HbbTV), a smart TV, etc. for example. The image display apparatus isapplicable to a smart phone, as needed.

Embodiments of the present invention will be described in detail withreference to the attached drawings, but it should be understood thatthey are merely illustrative of the present invention and should not beinterpreted as limiting the scope of the present invention.

In addition, although the terms used in the present invention areselected from generally known and used terms, some of the termsmentioned in the description of the present invention, the detailedmeanings of which are described in relevant parts of the descriptionherein, have been selected by the applicant at his or her discretion.Furthermore, the present invention must be understood, not simply by theactual terms used but by the meanings of each term lying within.

FIG. 1 illustrates the overall configuration of a broadcasting systemincluding an image display apparatus according to an embodiment of thepresent invention.

Referring to FIG. 1, the broadcasting system may include a ContentProvider (CP) 10, a Service Provider (SP) 20, a Network Provider (NP)30, and a Home Network End Device (HNED) 40. The HNED 40 corresponds to,for example, a client 100 which is an image display apparatus accordingto an embodiment of the present invention. As stated before, the imagedisplay apparatus may be a network TV, a smart TV, an Internet ProtocolTV (IPTV), etc.

The CP 10 creates and provides content. The CP 10 may be, for example, aterrestrial broadcaster, a cable System Operator (SO) or Multiple SystemOperator (MSO), a satellite broadcaster, or an Internet broadcaster, asillustrated in FIG. 1.

Besides broadcast content, the CP 10 may provide various applications,which will be described later in detail.

The SP 20 may provide content received from the CP 10 in a servicepackage. For instance, the SP 20 may package first terrestrialbroadcasting, second terrestrial broadcasting, cable broadcasting,satellite broadcasting, Internet broadcasting, and applications andprovide the package to users.

The SP 20 may unicast or multicast a service to the client 100. Unicastis a form of transmission in which information is sent from only onetransmitter to only one receiver. In other words, unicast transmissionis point-to-point, involving two nodes only. In an example of unicasttransmission, upon receipt of a request for data from a receiver, aserver transmits the data to only one receiver. Multicast is a type oftransmission or communication in which a transmitter transmits data to agroup of receivers. For example, a server may transmit data to aplurality of pre-registered receivers at one time. For multicastregistration, the Internet Group Management Protocol (IGMP) may be used.

The NP 30 may provide a network over which a service is provided to theclient 100. The client 100 may construct a home network and receive aservice over the home network.

Content transmitted in the above-described broadcasting system may beprotected through conditional access or content protection. CableCardand Downloadable Conditional Access System (DCAS) are examples ofconditional access or content protection.

The client 100 may also transmit content over a network. In this case,the client 100 serves as a CP and thus the CP 10 may receive contentfrom the client 100. Therefore, an interactive content service or dataservice can be provided.

FIG. 2 illustrates the overall configuration of a broadcasting systemincluding an image display apparatus according to another embodiment ofthe present invention.

Referring to FIG. 2, the image display apparatus 100 according toanother embodiment of the present invention is connected to a broadcastnetwork and the Internet. The image display apparatus 100 is, forexample, a network TV, a smart TV, an HbbTV, etc.

The image display apparatus 100 includes, for example, a broadcastinterface 101, a section filter 102, an Application Information Table(AIT) filter 103, an application data processor 104, a broadcast dataprocessor 111, a media player 106, an IP processor 107, an Internetinterface 108, and a runtime module 109.

The image display apparatus 100 receives AIT data, real-time broadcastcontent, application data, and stream events through the broadcastinterface 101. The real-time broadcast content may be referred to aslinear Audio/Video (A/V) content.

The section filter 102 performs section filtering on the four types ofdata received through the broadcast interface 101, and outputs the AITdata to the AIT filter 103, the linear A/V content to the broadcast dataprocessor 111, and the stream events and application data to theapplication data processor 104.

Meanwhile, the image display apparatus 100 receives non-linear A/Vcontent and application data through the Internet interface 108. Thenon-linear A/V content may be, for example, a Content On Demand (CoD)application.

The non-linear A/V content and the application data are transmitted tothe media player 106 and the runtime module 109, respectively.

The runtime module 109 includes, for example, an application manager anda browser as illustrated in FIG. 2. The application manager controls thelife cycle of an interactive application using the AIT data, forexample. The browser displays and processes the interactive application.

FIG. 3 is a diagram illustrating a signal flow for an operation forattaching to an SP and receiving channel information from the SP in theimage display apparatus illustrated in FIG. 1 or 2. Needless to say, theoperation illustrated in FIG. 3 is an embodiment, which should not beinterpreted as limiting the scope of the present invention.

Referring to FIG. 3, an SP performs an SP Discovery operation (S301) andthe image display apparatus transmits a Service Provider AttachmentRequest signal to the SP (S302). Upon completion of attachment to theSP, the image display apparatus receives provisioning information fromthe SP (S303). Further, the image display apparatus receives MasterSystem Information (SI) Tables, Virtual Channel Map Tables, VirtualChannel Description Tables, and Source Tables from the SP (S304 toS307).

More specifically, SP Discovery is a process by which SPs that provideIPTV services search for Service Discovery (SD) servers havinginformation about the offerings of the SPs.

In order to receive information about the SD servers, an SD serveraddress list can be detected, for example, using three methods,specifically use of an address preset in the image display apparatus oran address manually set by a user, Dynamic Host Configuration Protocol(DHCP)-based SP Discovery, and Domain Name System Service (DNSSRV)-based SP Discovery. The image display apparatus accesses a specificSD server using the SD server address list obtained through one of theabove three methods and receives a SP Discovery record from the specificSD server. The Service Provider Discovery record includes informationneeded to perform Service Discovery on an SP basis. The image displayapparatus then starts a Service Discovery operation using the SPDiscovery record. These operations can be performed in a push mode or apull mode.

The image display apparatus accesses an SP attachment server specifiedby an SP attachment locator included in the SP Discovery record andperforms a registration procedure (or a service attachment procedure).

Further, after accessing an authentication service server of an SPspecified by an SP authentication locator and performing anauthentication procedure, the image display apparatus may perform aservice authentication procedure.

After service attachment is successfully performed, a server maytransmit data in the form of a provision information table to the imagedisplay apparatus.

During service attachment, the image display apparatus may include anIdentifier (ID) and location information thereof in data and transmitthe data to the service attachment server. Thus the service attachmentserver may specify a service that the image display apparatus hassubscribed to based on the ID and location information. In addition, theservice attachment server provides, in the form of a provisioninginformation table, address information from which the image displayapparatus can obtain Service Information (SI). The address informationcorresponds to access information about a Master SI Table. This methodfacilitates provision of a customized service to each subscriber.

The SI is divided into a Master SI Table record for managing accessinformation and version information about a Virtual Channel Map, aVirtual Channel Map Table for providing a list of services in the formof a package, a Virtual Channel Description Table that contains detailsof each channel, and a Source Table that contains access informationabout actual services.

FIG. 4 is a detailed diagram of FIG. 3, illustrating a relationshipamong data in the SI.

Referring to FIG. 4, a Master SI Table contains information about thelocation and version of each Virtual Channel MAP.

Each Virtual Channel MAP is identified by its Virtual Channel MAPidentifier. VirtualChannelMAPVersion specifies the version number of theVirtual Channel MAP. If any of the tables connected to the Master SITable in the arrowed direction is modified, the versions of the modifiedtable and overlying tables thereof (up to the Master SI Table) areincremented. Accordingly, a change in any of the SI tables can bereadily identified by monitoring the Master SI Table.

For example, when the Source Table is changed, the version of the SourceTable is incremented and the version of the Virtual Channel DescriptionTable that references the Source Table is also incremented. Inconclusion, a change in any lower table leads to a change in its highertables and, eventually, a change in the Master SI Table.

One Master SI Table may exist for each SP. However, in the case whereservice configurations differ for regions or subscribers (or subscribergroups), an SP may have a plurality of Master SI Tables in order toprovide a customized service on a region, subscriber or subscriber groupbasis. Thus it is possible to provide a customized service to asubscriber according to a region in which the subscriber is located andsubscriber information regarding the subscriber.

A Virtual Channel Map Table may contain a list of one or more virtualchannels. A Virtual Channel Map includes not details of the channels butinformation about the locations of the details of the channels. In theVirtual Channel Map Table, VirtualChannelDescriptionLocation specifiesthe location of a Virtual Channel Description Table that providesvirtual channel descriptions.

The Virtual Channel Description Table contains the details of thevirtual channels. The Virtual Channel Description Table can be accessedusing VirtualChannelDescriptionLocation of the Virtual Channel MapTable.

A Source Table provides information necessary to access actual services(e.g. IP addresses, ports, AV Codecs, transmission protocols, etc.) on aservice basis.

The above-described Master SI Table, the Virtual Channel Map Table, theVirtual Channel Description Table and the Source Table are delivered infour logically separate flows, in a push mode or a pull mode. Forversion management, the Master SI Table may be multicast and thus aversion change can be monitored by receiving a multicast stream of theMaster SI Table.

FIG. 5 is a detailed block diagram of the image display apparatusillustrated in FIG. 1 or 2 according to an embodiment of the presentinvention. The structure of the image display apparatus in FIG. 5 ispurely exemplary and should not be interpreted as limiting the scope ofthe present invention.

Referring to FIG. 5, an image display apparatus 700 includes a networkinterface 701, a Transmission Control Protocol/Internet Protocol(TCP/IP) manager 702, a service delivery manager 703, a Demultiplexer(DEMUX) 705, a Program Specific Information (PSI) & (Program and SystemInformation Protocol (PSIP) and/or SI) decoder 704, a display A/V and OnScreen Display (OSD) module 708, a service control manager 709, aservice discovery manager 710, a metadata manager 712, an SI & metadataDataBase (DB) 711, a User Interface (UI) manager 714, and a servicemanager 713.

The network interface 701 transmits packets to and receives packets froma network. Specifically, the network interface 701 receives services andcontent from an SP over the network.

The TCP/IP manager 702 is involved in packet reception and transmissionof the image display apparatus 700, that is, packet delivery from asource to a destination. The TCP/IP manager 702 classifies receivedpackets according to appropriate protocols and outputs the classifiedpackets to the service delivery manager 705, the service discoverymanager 710, the service control manager 709, and the metadata manager712.

The service delivery manager 703 controls received service data. Forexample, when controlling real-time streaming data, the service deliverymanager 703 may use the Real-time Transport Protocol/Real-time TransportControl Protocol (RTP/RTCP). If real-time streaming data is transmittedover RTP/RTCP, the service delivery manager 703 parses the receivedreal-time streaming data using RTP and outputs the parsed real-timestreaming data to the DEMUX 705 or stores the parsed real-time streamingdata in the SI & metadata DB 711 under the control of the servicemanager 713. In addition, the service delivery manager 703 feeds backnetwork reception information to a server that provides the real-timestreaming data service using RTCP.

The DEMUX 705 demultiplexes a received packet into audio data, videodata and PSI data and outputs the audio data, video data and PSI data tothe audio decoder 706, the video decoder 707, and the PSI & (PSIP and/orSI) decoder 704, respectively.

The PSI & (PSIP and/or SI) decoder 704 decodes SI such as PSI. Morespecifically, the PSI & (PSIP and/or SI) decoder 704 decodes PSIsections, PSIP sections or SI sections received from the DEMUX 705.

The PSI & (PSIP and/or SI) decoder 704 constructs an SI DB by decodingthe received sections and stores the SI DB in the SI & metadata DB 711.

The audio decoder 706 and the video decoder 707 decode the audio dataand the video data received from the DEMUX 705 and output the decodedaudio and video data to a user through the display A/V and OSD module708.

The UI manager 714 and the service manager 713 manage the overall stateof the image display apparatus 700, provide UIs, and manage othermanagers.

The UI manager 714 provides a Graphical User Interface (GUI) in the formof an OSD and performs a reception operation corresponding to a keyinput received from the user. For example, upon receipt of a key inputsignal regarding channel selection from the user, the UI manager 714transmits the key input signal to the service manager 713.

The service manager 713 controls managers associated with services, suchas the service delivery manager 703, the service discovery manager 710,the service control manager 709, and the metadata manager 712.

The service manager 713 also makes a channel map and selects a channelusing the channel map according to the key input signal received fromthe UI manager 714. The service manager 713 sets the audio/video PacketID (PID) of the selected channel based on SI about the channel receivedfrom the PSI & (PSIP and/or SI) decoder 704.

The service discovery manager 710 provides information necessary toselect an SP that provides a service. Upon receipt of a channelselection signal from the service manager 713, the service discoverymanager 710 detects a service based on the channel selection signal.

The service control manager 709 takes charge of selecting and controlservices. For example, if a user selects live broadcasting, like aconventional broadcasting service, the service control manager selectsand controls the service using Internet Group Management Protocol (IGMP)or Real-Time Streaming Protocol (RTSP). If the user selects Video onDemand (VoD), the service control manager 709 selects and controls theservice. RTSP supports trick mode for real-time streaming. Further, theservice control manager 709 may initialize and manage a session throughan IP Multimedia Control (IMC) gateway using IP Multimedia Subsystem(IMS) and Session Initiation Protocol (SIP). The protocols are given byway of example and thus other protocols are also applicable according toother embodiments.

The metadata manager 712 manages metadata related to services and storesthe metadata in the SI & metadata DB 711.

The SI & metadata DB 711 stores the SI decoded by the PSI & (PSIP and/orSI) decoder 704, the metadata managed by the metadata manager 712, andthe information required to select an SP, received from the servicediscovery manager 710. The SI & metadata DB 711 may store setup data forthe system.

The SI & metadata DB 711 may be constructed in a Non-Volatile RAM(NVRAM) or a flash memory.

An IMS gateway 705 is a gateway equipped with functions needed to accessIMS-based IPTV services.

FIG. 6 is a detailed block diagram of the image display apparatusillustrated in FIG. 1 or 2 according to another embodiment of thepresent invention.

Referring to FIG. 6, an image display apparatus 100 according to anotherembodiment of the present invention includes a broadcasting receiver105, an external device interface 135, a memory 140, a user inputinterface 150, a controller 170, a display 180, an audio output unit185, a power supply 190, and a camera module. The broadcasting receiver105 may include a tuner 110, a demodulator 120 and a network interface130. As needed, the broadcasting receiver 105 may be configured so as toinclude only the tuner 110 and the demodulator 120 or only the networkinterface 130.

The tuner 110 selects a Radio Frequency (RF) broadcast signalcorresponding to a channel selected by a user from among a plurality ofRF broadcast signals received through an antenna and downconverts theselected RF broadcast signal into a digital Intermediate Frequency (IF)signal or an analog baseband A/V signal.

More specifically, if the selected RF broadcast signal is a digitalbroadcast signal, the tuner 110 downconverts the selected RF broadcastsignal into a digital IF signal DIF. On the other hand, if the selectedRF broadcast signal is an analog broadcast signal, the tuner 110downconverts the selected RF broadcast signal into an analog basebandA/V signal, CVBS/SIF. That is, the tuner 110 may be a hybrid tunercapable of processing not only digital broadcast signals but also analogbroadcast signals. The analog baseband A/V signal CVBS/SIF may bedirectly input to the controller 170.

The tuner 110 may be capable of receiving RF broadcast signals from anAdvanced Television Systems Committee (ATSC) single-carrier system orfrom a Digital Video Broadcasting (DVB) multi-carrier system.

The tuner 110 may sequentially select a number of RF broadcast signalscorresponding to all broadcast channels previously stored in the imagedisplay apparatus 100 by a channel add function from a plurality of RFsignals received through the antenna and may downconvert the selected RFbroadcast signals into IF signals or baseband A/V signals.

The demodulator 120 receives the digital IF signal DIF from the tuner110 and demodulates the digital IF signal DIF.

For example, if the digital IF signal DIF is an ATSC signal, thedemodulator 120 may perform 8-Vestigal SideBand (VSB) demodulation onthe digital IF signal DIF. The demodulator 120 may also perform channeldecoding. For channel decoding, the demodulator 120 may include aTrellis decoder, a de-interleaver and a Reed-Solomon decoder so as toperform Trellis decoding, de-interleaving and Reed-Solomon decoding.

For example, if the digital IF signal DIF is a DVB signal, thedemodulator 120 performs Coded Orthogonal Frequency Division MultipleAccess (COFDMA) demodulation upon the digital IF signal DIF. Thedemodulator 120 may also perform channel decoding. For channel decoding,the demodulator 120 may include a convolution decoder, a de-interleaver,and a Reed-Solomon decoder so as to perform convolution decoding,de-interleaving, and Reed-Solomon decoding.

The demodulator 120 may perform demodulation and channel decoding on thedigital IF signal DIF, thereby obtaining a stream signal TS. The streamsignal TS may be a signal in which a video signal, an audio signal and adata signal are multiplexed. For example, the stream signal TS may be anMPEG-2 TS in which an MPEG-2 video signal and a Dolby AC-3 audio signalare multiplexed. An MPEG-2 TS may include a 4-byte header and a 184-bytepayload.

In order to properly handle not only ATSC signals but also DVB signals,the demodulator 120 may include an ATSC demodulator and a DVBdemodulator.

The stream signal TS may be input to the controller 170 and thussubjected to demultiplexing and A/V signal processing. The processedvideo and audio signals are output to the display 180 and the audiooutput unit 185, respectively.

The external device interface 135 may serve as an interface between anexternal device and the image display apparatus 100. For interfacing,the external device interface 135 may include an A/V Input/Output (I/O)unit and/or a wireless communication module.

The external device interface 135 may be connected to an external devicesuch as a Digital Versatile Disk (DVD) player, a Blu-ray player, a gameconsole, a camera, a camcorder, or a computer (e.g., a laptop computer),wirelessly or by wire. Then, the external device interface 135externally receives video, audio, and/or data signals from the externaldevice and transmits the received input signals to the controller 170.In addition, the external device interface 135 may output video, audio,and data signals processed by the controller 170 to the external device.In order to receive or transmit audio, video and data signals from or tothe external device, the external device interface 135 includes the A/VI/O unit and/or the wireless communication module.

The A/V I/O unit of the external device interface 135 may include aUniversal Serial Bus (USB) port, a Composite Video Banking Sync (CVBS)port, a Component port, a Super-video (S-video) (analog) port, a DigitalVisual Interface (DVI) port, a High-Definition Multimedia Interface(HDMI) port, a Red-Green-Blue (RGB) port, and a D-sub port.

The wireless communication module of the external device interface 135may perform short-range wireless communication with other electronicdevices. For short-range wireless communication, the wirelesscommunication module may use Bluetooth, Radio-Frequency IDentification(RFID), Infrared Data Association (IrDA), Ultra WideBand (UWB), ZigBee,and Digital Living Network Alliance (DLNA).

The external device interface 135 may be connected to various set-topboxes through at least one of the above-described ports and may thusreceive data from or transmit data to the various set-top boxes.

The external device interface 135 may receive applications or anapplication list from an adjacent external device and provide theapplications or the application list to the controller 170 or the memory140.

The network interface 130 serves as an interface between the imagedisplay apparatus 100 and a wired/wireless network such as the Internet.The network interface 130 may include an Ethernet port for connection toa wired network. The wireless communication module of the externalsignal I/O unit 128 may wirelessly access the Internet. For connectionto wireless networks, the network interface 130 may use Wireless LocalArea Network (WLAN) (i.e., Wi-Fi), Wireless Broadband (WiBro), WorldInteroperability for Microwave Access (WiMax), and High Speed DownlinkPacket Access (HSDPA).

The network interface 130 may transmit data to or receive data fromanother user or electronic device over a connected network or anothernetwork linked to the connected network. Especially, the networkinterface 130 may transmit data stored in the image display apparatus100 to a user or electronic device selected from among users orelectronic devices pre-registered with the image display apparatus 100.

The network interface 130 may access a specific Web page over aconnected network or another network linked to the connected network.That is, the network interface 130 may access a specific Web page over anetwork and transmit or receive data to or from a server. Additionally,the network interface 130 may receive content or data from a CP or anNP. Specifically, the network interface 130 may receive content such asmovies, advertisements, games, VoD files, and broadcast signals, andinformation related to the content from a CP or an NP. Also, the networkinterface 130 may receive update information about firmware and updatefiles of the firmware from the NP. The network interface 130 maytransmit data over the Internet or to the CP or the NP.

The network interface 130 may selectively receive a desired applicationamong open applications over a network.

In an embodiment of the present invention, when a game application isexecuted in the image display apparatus 100, the network interface 130may transmit data to or receive data from a user terminal connected tothe image display apparatus 100 through a network. In addition, thenetwork interface 130 may transmit specific data to or receive specificdata from a server that records game scores.

The memory 140 may store various programs necessary for the controller170 to process and control signals, and may also store processed video,audio and data signals.

The memory 140 may temporarily store a video, audio and/or data signalreceived from the external device interface 135 or the network interface130. The memory 140 may store information about broadcast channels bythe channel-add function.

The memory 140 may store applications or a list of applications receivedfrom the external device interface 135 or the network interface 130.

The memory 140 may store a variety of platforms which will be describedlater.

In an embodiment of the present invention, when the image displayapparatus 100 executes a game application, the memory 140 may storeuser-specific information and game play information about a userterminal used as a game controller.

The memory 140 may include, for example, at least one of a flashmemory-type storage medium, a hard disk-type storage medium, amultimedia card micro-type storage medium, a card-type memory (e.g. aSecure Digital (SD) or eXtreme Digital (XD) memory), a Random AccessMemory (RAM), or a Read-Only Memory (ROM) such as an ElectricallyErasable and Programmable Read Only Memory. The image display apparatus100 may reproduce content stored in the memory 140 (e.g. video files,still image files, music files, text files, and application files) tothe user.

While the memory 140 is shown in FIG. 6 as configured separately fromthe controller 170, to which the present invention is not limited, thememory 140 may be incorporated into the controller 170, for example.

The user input interface 150 transmits a signal received from the userto the controller 170 or transmits a signal received from the controller170 to the user.

For example, the user input interface 150 may receive various user inputsignals such as a power-on/off signal, a channel selection signal, and ascreen setting signal from a remote controller 200 or may transmit asignal received from the controller 170 to the remote controller 200,according to various communication schemes, for example, RFcommunication and IR communication.

For example, the user input interface 150 may provide the controller 170with user input signals or control signals received from local keys,such as inputs of a power key, a channel key, and a volume key, andsetting values.

Also, the user input interface 150 may transmit a control signalreceived from a sensor unit for sensing a user gesture to the controller170 or transmit a signal received from the controller 170 to the sensorunit. The sensor unit may include a touch sensor, a voice sensor, aposition sensor, a motion sensor, etc.

The controller 170 may demultiplex the stream signal TS received fromthe tuner 110, the demodulator 120, or the external device interface 135into a number of signals and process the demultiplexed signals intoaudio and video data.

The video signal processed by the controller 170 may be displayed as animage on the display 180. The video signal processed by the controller170 may also be transmitted to an external output device through theexternal device interface 135.

The audio signal processed by the controller 170 may be output to theaudio output unit 185. Also, the audio signal processed by thecontroller 170 may be transmitted to the external output device throughthe external device interface 135.

While not shown in FIG. 6, the controller 170 may include a DEMUX and avideo processor, which will be described later with reference to FIG.10.

In addition, the controller 170 may provide overall control to the imagedisplay apparatus 100. For example, the controller 170 may control thetuner 110 to select an RF broadcast signal corresponding to auser-selected channel or a pre-stored channel.

The controller 170 may control the image display apparatus 100 accordingto a user command received through the user input interface 150 oraccording to an internal program. Especially the controller 170 mayaccess a network and download an application or application listselected by the user to the image display apparatus 100 over thenetwork.

For example, the controller 170 controls the tuner 110 to receive achannel selected according to a specific channel selection commandreceived through the user input interface 150, and processes a video,audio and/or data signal of the selected channel. The controller 170outputs the processed video or audio signal along with information aboutthe user-selected channel to the display 180 or the audio output unit185.

In another example, the controller 170 outputs a video or audio signalreceived from an external device such as a camera or a camcorder throughthe external device interface 135 to the display 180 or the audio outputunit 185 according to an external device video playback command receivedthrough the external device interface 150.

The controller 170 may control the display 180 to display images. Forinstance, the controller 170 may control the display 180 to display abroadcast image received from the tuner 110, an external input imagereceived through the external device interface 135, an image receivedthrough the network interface 130, or an image stored in the memory 140.The image displayed on the display 180 may be a Two-Dimensional (2D) orThree-Dimensional (3D) still image or moving picture.

The controller 170 may control content playback. The content may includeany content stored in the image display apparatus 100, receivedbroadcast content, and external input content.

The controller 170 may control transmission of the game play informationabout the game application to a specific server connected to the imagedisplay apparatus 100 over a network through the network interface 130.

As another embodiment, upon receipt of information about a change in thegame play information from the server through the network interface 130,the controller 170 may control output of a notification message in apredetermined area of the display 180.

The image display apparatus 100 may further include a channel browsingprocessor for generating thumbnail images corresponding to channelsignals or external input signals.

The channel browsing processor may extract some of the video frames ofeach of stream signals TS received from the demodulator 120 or streamsignals received from the external device interface 135 and display theextracted video frames on the display 180 as thumbnail images. Thethumbnail images may be directly output to the controller 170 or may beoutput after being encoded. Also, it is possible to encode the thumbnailimages into a stream and output the stream to the controller 170. Thecontroller 170 may display a thumbnail list including a plurality ofreceived thumbnail images on the display 180. The thumbnail images maybe updated sequentially or simultaneously in the thumbnail list.Therefore, the user can readily identify the content of broadcastprograms received through a plurality of channels.

The display 180 may convert a processed video signal, a processed datasignal, and an OSD signal received from the controller 170 or a videosignal and a data signal received from the external device interface 135into RGB signals, thereby generating driving signals.

The display 180 may be various types of displays such as a PlasmaDisplay Panel (PDP), a Liquid Crystal Display (LCD), an OrganicLight-Emitting Diode (OLED) display, a flexible display, and a 3Ddisplay.

The display 180 may also be a touch screen that can be used not only asan output device but also as an input device.

The audio output unit 185 may receive a processed audio signal (e.g., astereo signal, a 3.1-channel signal or a 5.1-channel signal) from thecontroller 170 and output the received audio signal as sound. The audiooutput unit 185 may employ various speaker configurations.

To sense a user gesture, the image display apparatus 100 may furtherinclude the sensor unit that has at least one of a touch sensor, a voicesensor, a position sensor, and a motion sensor, as stated before. Asignal sensed by the sensor unit may be output to the controller 170through the user input interface 150.

The image display apparatus 100 may further include the camera unit forcapturing images of a user. Image information captured by the cameraunit may be input to the controller 170.

The controller 170 may sense a user gesture from an image captured bythe camera unit or a signal sensed by the sensor unit, or by combiningthe captured image and the sensed signal.

The power supply 190 supplies power to the image display apparatus 100.Particularly, the power supply 190 may supply power to the controller170, the display 180, and the audio output unit 185, which may beimplemented as a System On Chip (SOC).

For supplying power, the power supply 190 may include a converter forconverting Alternating Current (AC) into Direct Current (DC). If thedisplay 180 is configured with, for example, a liquid crystal panelhaving a plurality of backlight lamps, the power supply 190 may furtherinclude an inverter capable of performing Pulse Width Modulation (PWM)for luminance change or dimming driving.

The remote controller 200 transmits a user input to the user inputinterface 150. For transmission of user input, the remote controller 200may use various communication techniques such as Bluetooth, RFcommunication, IR communication, UWB and ZigBee.

In addition, the remote controller 200 may receive a video signal, anaudio signal or a data signal from the user input interface 150 andoutput the received signals visually, audibly or as vibrations.

The above-described image display apparatus 100 may be a fixed digitalbroadcast receiver capable of receiving at least one of ATSC (8-VSB)broadcast programs, DVB-T (COFDM) broadcast programs, and ISDB-T(BST-OFDM) broadcast programs.

The block diagram of the image display apparatus 100 illustrated in FIG.6 is purely exemplary. Depending upon the specifications of the imagedisplay apparatus 100 in actual implementation, the components of theimage display apparatus 100 may be combined or omitted or new componentsmay be added. That is, two or more components are incorporated into onecomponent or one component may be configured as separate components, asneeded. In addition, the function of each block is described for thepurpose of describing the embodiment of the present invention and thusspecific operations or devices should not be construed as limiting thescope and spirit of the present invention.

Unlike the configuration illustrated in FIG. 6, the image displayapparatus 100 may be configured so as to receive and playback videocontent through the network interface 130 or the external deviceinterface 135, without the tuner 100 and the demodulator 120.

The image display apparatus 100 is an example of image signal processingapparatus that processes a stored image or an input image. Otherexamples of the image signal processing apparatus include a set-top boxwithout the display 180 and the audio output unit 185, a DVD player, aBlu-ray player, a game console, and a computer. The set-top box will bedescribed later with reference to FIGS. 7 and 8.

FIGS. 7 and 8 are block diagrams illustrating either of the imagedisplay apparatuses separately as a set-top box and a display deviceaccording to embodiments of the present invention.

Referring to FIG. 7, a set-top box 250 and a display device 300 maytransmit or receive data wirelessly or by wire.

The set-top box 250 may include a network interface 255, a memory 258, asignal processor 260, a user input interface 263, and an external deviceinterface 265.

The network interface 255 serves as an interface between the set-top box250 and a wired/wireless network such as the Internet. The networkinterface 255 may transmit data to or receive data from another user oranother electronic device over a connected network or over anothernetwork linked to the connected network.

The memory 258 may store programs necessary for the signal processor 260to process and control signals and temporarily store a video, audioand/or data signal received from the external device interface 265 orthe network interface 255. The memory 258 may also store platformsillustrated in FIGS. 11 and 12, as described later.

The signal processor 260 processes an input signal. For example, thesignal processor 260 may demultiplex or decode an input video or audiosignal. For signal processing, the signal processor 260 may include avideo decoder or an audio decoder. The processed video or audio signalmay be transmitted to the display device 300 through the external deviceinterface 265.

The user input interface 263 transmits a signal received from the userto the signal processor 260 or a signal received from the signalprocessor 260 to the user. For example, the user input interface 263 mayreceive various control signals such as a power on/off signal, anoperation input signal, and a setting input signal through a local keyor the remote controller 200 and output the control signals to thesignal processor 260.

The external device interface 265 serves as an interface between theset-top box 250 and an external device that is connected wirelessly orby wire, particularly the display device 300, for signal transmission orreception. The external device interface 265 may also interface with anexternal device such as a game console, a camera, a camcorder, and acomputer (e.g. a laptop computer), for data transmission or reception.

The set-top box 250 may further include a media input unit for mediaplayback. The media input unit may be a Blu-ray input unit, for example.That is, the set-top box 250 may include a Blu-ray player. After signalprocessing such as demultiplexing or decoding in the signal processor260, a media signal from a Blu-ray disk may be transmitted to thedisplay device 300 through the external device interface 265 so as to bedisplayed on the display device 300.

The display device 300 may include a tuner 270, an external deviceinterface 273, a demodulator 275, a memory 278, a controller 280, a userinput interface 283, a display 290, and an audio output unit 295.

The tuner 270, the demodulator 275, the memory 278, the controller 280,the user input interface 283, the display 290, and the audio output unit295 are identical respectively to the tuner 110, the demodulator 120,the memory 140, the controller 170, the user input interface 150, thedisplay 180, and the audio output unit 185 illustrated in FIG. 6 andthus a description thereof is not provided herein.

The external device interface 273 serves as an interface between thedisplay device 300 and a wireless or wired external device, particularlythe set-top box 250, for data transmission or reception.

Hence, a video signal or an audio signal received through the set-topbox 250 is output through the display 290 or the audio output unit 295through the controller 280.

Referring to FIG. 8, the configuration of the set-top box 250 and thedisplay device 300 illustrated in FIG. 8 is similar to that of theset-top box 250 and the display device 300 illustrated in FIG. 7, exceptthat the tuner 270 and the demodulator 275 reside in the set-top box250, not in the display device 300. Thus the following description isgiven focusing on such difference.

The signal processor 260 may process a broadcast signal received throughthe tuner 270 and the demodulator 275. The user input interface 263 mayreceive a channel selection input, a channel store input, etc.

FIG. 9 illustrates an operation for communicating with third devices ineither of the image display apparatuses according to an embodiment ofthe present invention. The image display apparatus illustrated in FIG. 9may be one of the afore-described image display apparatuses according tothe embodiments of the present invention.

Referring to FIG. 9, the image display apparatus 100 may communicatewith a broadcasting station 210, a network server 220, or an externaldevice 230.

The image display apparatus 100 may receive a broadcast signal includinga video signal from the broadcasting station 210. The image displayapparatus 100 may process the audio and video signals of the broadcastsignal or the data signal of the broadcast signal, suitably fortransmission from the image display apparatus 100. The image displayapparatus 100 may output images or sound based on the processed video oraudio signal.

Meanwhile, the image display apparatus 100 may communicate with thenetwork server 220. The network server 200 is capable of transmittingsignals to and receiving signals from the image display apparatus 100over a network. For example, the network server 220 may be a portableterminal that can be connected to the image display apparatus 100through a wired or wireless base station. In addition, the networkserver 200 may provide content to the image display apparatus 100 overthe Internet. A CP may provide content to the image display apparatus100 through the network server 220.

The image display apparatus 100 may communicate with the external device230. The external device 230 can transmit and receive signals directlyto and from the image display apparatus 100 wirelessly or by wire. Forinstance, the external device 230 may be a media memory device or aplayer. That is, the external device 230 may be any of a camera, a DVDplayer, a Blu-ray player, a PC, etc.

The broadcasting station 210, the network server 220 or the externaldevice 230 may transmit a signal including a video signal to the imagedisplay apparatus 100. The image display apparatus 100 may display animage based on the video signal included in the received signal. Also,the image display apparatus 100 may transmit a signal received from thebroadcasting station 210 or the network server 220 to the externaldevice 230 and may transmit a signal received from the external device230 to the broadcasting station 210 or the network server 220. That is,the image display apparatus 100 may transmit content included in signalsreceived from the broadcasting station 210, the network server 220, andthe external device 230, as well as playback the content immediately.

FIG. 10 is a block diagram of the controller illustrated in FIG. 6.

Referring to FIG. 10, the controller 170 may include a DEMUX 310, avideo processor 320, an OSD generator 340, a mixer 350, a Frame RateConverter (FRC) 355, and a formatter 360 according to an embodiment ofthe present invention. The controller 170 may further include an audioprocessor and a data processor.

The DEMUX 310 demultiplexes an input stream. For example, the DEMUX 310may demultiplex an MPEG-2 TS into a video signal, an audio signal, and adata signal. The input stream signal may be received from the tuner 110,the demodulator 120 or the external device interface 135.

The video processor 320 may process the demultiplexed video signal. Forvideo signal processing, the video processor 320 may include a videodecoder 325 and a scaler 335.

The video decoder 325 decodes the demultiplexed video signal and thescaler 335 scales the resolution of the decoded video signal so that thevideo signal can be displayed on the display 180.

The video decoder 325 may be provided with decoders that operate basedon various standards.

If the demultiplexed video signal is, for example, an MPEC-2 encodedvideo signal, the video signal may be decoded by an MPEC-2 decoder.

On the other hand, if the video signal is an H.264-encoded DMB orDVB-handheld (DVB-H) signal, the video signal may be decoded by an H.264decoder.

The video signal decoded by the video processor 320 is provided to themixer 350.

The OSD generator 340 generates an OSD signal autonomously or accordingto user input. For example, the OSD generator 340 may generate signalsby which a variety of information is displayed as images or text on thedisplay 180, according to control signals received from the user inputinterface 150. The OSD signal may include various data such as a UI, avariety of menu screens, widgets, icons, etc.

For example, the OSD generator 340 may generate a signal by whichsubtitles are displayed for a broadcast image or Electronic ProgramGuide (EPG)-based broadcasting information.

The mixer 350 may mix the decoded video signal with the OSD signal andoutput the mixed signal to the formatter 360. As the decoded broadcastvideo signal or the external input signal is mixed with the OSD signal,an OSD may be overlaid on the broadcast image or the external inputimage.

The FRC 355 may change the frame rate of an input image. For example, aframe rate of 60 Hz is converted into a frame rate of 120 or 240 Hz.When the frame rate is to be changed from 60 Hz to 120 Hz, a first frameis inserted between the first frame and a second frame, or a predictedthird frame is inserted between the first and second frames. If theframe rate is to be changed from 60 Hz to 240 Hz, three identical framesor three predicted frames are inserted between the first and secondframes. It is also possible to maintain the frame rate of the inputimage without frame rate conversion.

The formatter 360 changes the format of the signal received from the FRC355 to be suitable for the display 180. For example, the formatter 360may convert a received signal into an RGB data signal. The RGB signalmay be output in the form of a Low Voltage Differential Signal (LVDS) ormini-LVDS.

The audio processor of the controller 170 may process the demultiplexedaudio signal. For audio signal processing, the audio processor may havea plurality of decoders.

If the demultiplexed audio signal is a coded audio signal, the audioprocessor of the controller 170 may decode the audio signal. Forexample, the demultiplexed audio signal may be decoded by an MPEG-2decoder, an MPEG-4 decoder, an Advanced Audio Coding (AAC) decoder, oran AC-3 decoder.

The audio processor of the controller 170 may also adjust the bass,treble or volume of the audio signal.

The data processor of the controller 170 may process the data signalobtained by demultiplexing the input stream signal. For example, if thedata signal is an encoded signal such as an EPG which includesbroadcasting information specifying the start time, end time, etc. ofscheduled broadcast TV or radio programs, the controller 170 may decodethe data signal. Examples of an EPG include ATSC-Program and SystemInformation Protocol (PSIP) information and DVB-Service Information(SI).

ATSC-PSIP information or DVB-SI may be included in the header of a TS,i.e., a 4-byte header of an MPEG-2 TS.

The block diagram of the controller 170 illustrated in FIG. 10 is anembodiment of the present invention. Depending upon the specificationsof the controller 170, the components of the controller 170 may becombined, or omitted. Or new components are added to the controller 170.

FIG. 11 illustrates a platform architecture for either of the imagedisplay apparatuses according to an embodiment of the present inventionand FIG. 12 illustrates a platform architecture for either of the imagedisplay apparatuses according to another embodiment of the presentinvention.

A platform for either of the image display apparatuses may have OS-basedsoftware to implement the above-described various operations accordingto an embodiment of the present invention.

Referring to FIG. 11, a platform for either of the image displayapparatuses is a separate type according to an embodiment of the presentinvention. The platform may be designed separately as a legacy systemplatform 400 and a smart system platform 405. An OS kernel 410 may beshared between the legacy system platform 400 and the smart systemplatform 405.

The legacy system platform 400 may include a stack of a driver 420,middleware 430, and an application layer 450 on the OS kernel 410.

On the other hand, the smart system platform 405 may include a stack ofa library 435, a framework 440, and an application layer 455 on the OSkernel 410.

The OS kernel 410 is the core of an operating system. When the imagedisplay apparatus is driven, the OS kernel 410 may be responsible foroperation of at least one of hardware drivers, security protection forhardware and processors in the image display apparatus, efficientmanagement of system resources, memory management, hardware interfacingby hardware abstraction, multi-processing, or scheduling associated withthe multi-processing. Meanwhile, the OS kernel 410 may further performpower management.

The hardware drivers of the OS kernel 410 may include, for example, atleast one of a display driver, a Wi-Fi driver, a Bluetooth driver, a USBdriver, an audio driver, a power manager, a binder driver, or a memorydriver.

Alternatively or additionally, the hardware drivers of the OS kernel 410may be drivers for hardware devices within the OS kernel 410. Thehardware drivers may include a character device driver, a block devicedriver, and a network device driver. The block device driver may need abuffer for buffering data on a block basis, because data is transmittedon a block basis. The character device driver may not need a buffersince data is transmitted on a basic data unit basis, that is, on acharacter basis.

The OS kernel 410 may be implemented based on any of various OSs such asUnix (Linux), Windows, etc. The OS kernel 410 may be a general-purposeopen OS kernel which can be implemented in other electronic devices.

The driver 420 is interposed between the OS kernel 410 and themiddleware 430. Along with the middleware 430, the driver 420 drivesdevices for operations of the application layer 450. For example, thedriver 420 may include a driver(s) for a microcomputer, a displaymodule, a Graphic Processing Unit (GPU), the FRC, a General-PurposeInput/Output (GPIO) pin, a High-Definition Multimedia Interface (HDMI),a System Decoder (SDEC) or DEMUX, a Video Decoder (VDEC), an AudioDecoder (ADEC), a Personal Video Recorder (PVR), and/or anInter-Integrated Circuit (I2C). These drivers operate in conjunctionwith the hardware drivers of the OS kernel 410.

In addition, the driver 420 may further include a driver for the remotecontroller 200, especially a pointing device to be described below. Theremote controller driver may reside in the OS kernel 410 or themiddleware 430, instead of the driver 420.

The middleware 430 resides between the OS kernel 410 and the applicationlayer 450. The middleware 430 may mediate between different hardwaredevices or different software programs, for data transmission andreception between the hardware devices or the software programs.Therefore, the middleware 430 can provide standard interfaces, supportvarious environments, and enable interaction between tasks conforming toheterogeneous communication protocols.

Examples of the middleware 430 in the legacy system platform 400 mayinclude Multimedia and Hypermedia information coding Experts Group(MHEG) and Advanced Common Application Platform (ACAP) as databroadcasting-related middleware, PSIP or SI middleware as broadcastinginformation-related middleware, and DLNA middleware as peripheral devicecommunication-related middleware.

The application layer 450 that runs atop the middleware 430 in thelegacy system platform 400 may include, for example, UI applicationsassociated with various menus in the image display apparatus. Theapplication layer 450 may allow editing and updating over a network byuser selection. With use of the application layer 450, the user mayenter a desired menu among various UIs by manipulating the remotecontroller 210 while viewing a broadcast program.

The application layer 450 may further include at least one of a TV guideapplication, a Bluetooth application, a reservation application, aDigital Video Recorder (DVR) application, and a hotkey application.

In the smart system platform 405, the library 435 is positioned betweenthe OS kernel 410 and the framework 440, forming the basis of theframework 440. For example, the library 435 may include Secure SocketLayer (SSL) being a security-related library, WebKit being a Webengine-related library, c library (libc), and Media Framework being amedia-related library specifying, for example, a video format and anaudio format. The library 435 may be written in C or C++. Also, thelibrary 435 may be exposed to a developer through the framework 440.

The library 435 may include a runtime 437 with a core Java library and aVirtual Machine (VM). The runtime 437 and the library 435 form the basisof the framework 440.

The VM may be a virtual machine that enables concurrent execution of aplurality of instances, that is, multi-tasking. For each application ofthe application layer 455, a VM may be allocated and executed. Forscheduling or interconnection between instances, the binder driver ofthe OS kernel 410 may operate.

The binder driver and the runtime 437 may connect Java applications toC-based libraries.

The library 435 and the runtime 437 may correspond to the middleware 430of the legacy system platform 400.

In the smart system platform 405, the framework 440 includes programs onwhich applications of the application layer 455 are based. The framework440 is compatible with any application and may allow component reuse,movement or exchange. The framework 440 may include supporting programsand programs for interconnecting different software components. Forexample, the framework 440 may include an activity manager related toactivities of applications, a notification manager, and a CP forabstracting common information between applications. This framework 440may be written in Java.

The application layer 455 on top of the framework 440 includes a varietyof programs that are executed and displayed in the image displayapparatus. The application layer 455 may include, for example, a coreapplication that is a suit having at least one solution of e-mail, ShortMessage Service (SMS), calendar, map, or browser. The application layer455 may be written in Java.

In the application layer 455, applications may be categorized intouser-undeletable applications 465 stored in the image display apparatus100 that cannot be modified and user-installable or user-deletableapplications 475 that are downloaded from an external device or anetwork and stored in the image display apparatus.

With the applications of the application layer 455, a variety offunctions such as Internet telephony, VoD, Web album, Social NetworkingService (SNS), Location-Based Service (LBS), map service, Web browsing,and application search may be performed through network access. Inaddition, other functions such as gaming and schedule management may beperformed by the applications.

Referring to FIG. 12, a platform for the image display apparatusaccording to another embodiment of the present invention is anintegrated type. The integrated platform may include an OS kernel 510, adriver 520, middleware 530, a framework 540, and an application layer550.

Compared to the separate-type platform illustrated in FIG. 11, theintegrated-type platform is characterized by the absence of the library435 and the application layer 550 being an integrated layer. The driver520 and the framework 540 correspond to the driver 420 and the framework440 of FIG. 5, respectively.

The library 435 of FIG. 11 may be incorporated into the middleware 530.That is, the middleware 530 may include both the legacy systemmiddleware and the image display system middleware. As described before,the legacy system middleware includes MHEG or ACAP as databroadcasting-related middleware, PSIP or SI middleware as broadcastinginformation-related middleware, and DLNA middleware as peripheral devicecommunication-related middleware, whereas the image display systemmiddleware includes SSL as a security-related library, WebKit as a Webengine-related library, libc, and Media Framework as a media-relatedlibrary. The middleware 530 may further include the afore-describedruntime.

The application layer 550 may include a menu-related application, a TVguide application, a reservation application, etc. as legacy systemapplications, and e-mail, SMS, a calendar, a map, and a browser as imagedisplay system applications.

In the application layer 550, applications may be categorized intouser-undeletable applications 565 that are stored in the image displayapparatus and user-installable or user-deletable applications 575 thatare downloaded from an external device or a network and stored in theimage display apparatus.

Based on the afore-described platforms illustrated in FIGS. 11 and 12, avariety of Application Programming Interfaces (APIs) and SoftwareDevelopment Kits (SDKs) necessary to develop applications may be opened.APIs may be implemented functions that provide connectivity to specificsub-routines, for execution of the functions within a program. Or APIsmay be implemented programs.

For example, sources related to hardware drivers of the OS kernel 410,such as a display driver, a WiFi driver, a Bluetooth driver, a USBdriver or an audio driver, may be opened. Related sources within thedriver 420 such as a driver for a microcomputer, a display module, aGPU, an FRC, an SDEC, a VDEC, an ADEC or a pointing device may beopened. In addition, sources related to PSIP or SI middleware asbroadcasting information-related middleware or sources related to DLNAmiddleware may be opened.

Such various open APIs allow developers to create applicationsexecutable in the image display apparatus 100 or applications requiredto control operations of the image display apparatus 100 based on theplatforms illustrated in FIGS. 11 and 12.

The platforms illustrated in FIGS. 11 and 12 may be general-purpose onesthat can be implemented in many other electronic devices as well as inimage display apparatuses. The platforms may be stored or loaded in thememory 140, the controller 170, or any other processor. To executeapplications, an additional application processor may be furtherprovided.

FIG. 13 illustrates a method for controlling either of the image displayapparatuses using a remote controller according to an embodiment of thepresent invention.

FIG. 13(a) illustrates a pointer 205 representing movement of the remotecontroller 200 displayed on the display 180.

The user may move or rotate the remote controller 200 up and down, sideto side (FIG. 13(b)), and back and forth (FIG. 13(c)). Since the pointer205 moves in accordance with the movement of the remote controller 200,the remote controller 200 may be referred to as a pointing device.

Referring to FIG. 13(b), if the user moves the remote controller 200 tothe left, the pointer 205 moves to the left on the display 180. A sensorof the remote controller 200 detects the movement of the remotecontroller 200 and transmits motion information corresponding to theresult of the detection to the image display apparatus. Then, the imagedisplay apparatus determines the movement of the remote controller 200based on the motion information received from the remote controller 200,and calculates the coordinates of a target point to which the pointer205 should be shifted in accordance with the movement of the remotecontroller 200 based on the result of the determination. The imagedisplay apparatus then displays the pointer 205 at the calculatedcoordinates.

Referring to FIG. 13(c), while pressing a predetermined button of theremote controller 200, the user moves the remote controller 200 awayfrom the display 180. Then, a selected area corresponding to the pointer205 may be zoomed in on and enlarged on the display 180. On thecontrary, if the user moves the remote controller 200 toward the display180, the selection area corresponding to the pointer 205 is zoomed outand thus contracted on the display 180. The opposite case is possible.That is, when the remote controller 200 moves away from the display 180,the selection area may be zoomed out and when the remote controller 200approaches the display 180, the selection area may be zoomed in.

With the predetermined button pressed in the remote controller 200, theup, down, left and right movements of the remote controller 200 may beignored. That is, when the remote controller 200 moves away from orapproaches the display 180, only the back and forth movements of theremote controller 200 are sensed, while the up, down, left and rightmovements of the remote controller 200 are ignored. Unless thepredetermined button is pressed in the remote controller 200, thepointer 205 moves in accordance with the up, down, left or rightmovement of the remote controller 200.

The speed and direction of the pointer 205 may correspond to the speedand direction of the remote controller 200.

The pointer 205 is an object displayed on the display 180 incorrespondence with the movement of the remote controller 200.Therefore, the pointer 205 may have various shapes other than the arrowillustrated in FIG. 13. For example, the pointer 205 may be a dot, acursor, a prompt, a thick outline, etc. The pointer 205 may be displayedacross a plurality of points, such as a line and a surface, as well asat a single point on horizontal and vertical axes.

The image display apparatuses according to the embodiments of thepresent invention are capable of full browsing when displaying a mailservice page. Therefore, the user can use the mail service conveniently.

FIG. 19 is a flowchart illustrating a method for operating an imagedisplay apparatus according to an embodiment of the present invention,and FIGS. 20 to 45 are views referred to for describing the method foroperating an image display apparatus illustrated in FIG. 19.

Referring to FIG. 19, the image display apparatus 100 enters a setupmenu (S1105). Specifically, the controller 170 enters the setup menuaccording to a control signal received from a local key or the remotecontroller 200.

FIG. 21 illustrates exemplary selection of a setup object 1318 using thepointer 205 that moves in correspondence with movement of the remotecontroller 200, with a broadcast image 1315 and the setup object 1318displayed on the display 180. Upon selection of the setup object 1318, asetup menu 1410 appears on the display 180, as illustrated in FIG. 22.

In FIG. 21, the broadcast image 1315 is displayed along with varioustypes of content, by way of example.

The screen configuration illustrated in FIG. 21 may be a default screenconfiguration for a smart TV. The screen may be set as an initial screenthat is displayed when the image display apparatus 100 is powered on, oras a default screen that is displayed when a local key or a Home key ofthe remote controller 200 is manipulated. A card object area and anapplication menu area may be defined on the screen.

The card object area may include a plurality of card objects 1310, 1330and 1350 classified according to content sources. In FIG. 21, the cardobject 1310 is named BROADCAST and displays a broadcast image. The cardobject 1330 is named NETCAST and provides a CP list. The card object1350, which is named APP STORE, provides a list of applications. Othercard objects may further be included in the card object area, such as acard object for providing a thumbnail list of broadcast channels, a cardobject for providing a program list, a card object for providing areserved program list, and a card object for providing a media listavailable in a device.

The BROADCAST card object 1310 may contain a broadcast image 1315, anobject 1316 representing an external device, and the setup object 1318.Upon selection of the setup object 1318, the setup menu 1410 appears sothat the user can set login information (an ID and a password) for aplurality of Social Network Services (SNSs), as illustrated in FIG. 22.

The NETCAST card object 1330 may contain a CP list. While Yakoo,Metflix, weather.com, Picason, and My tube are shown as CPs in the CPlist in FIG. 21, others may be displayed.

The APP STORE card object 1350 may contain a list of applicationsavailable in an APP STORE. The applications may be sorted, for example,by popularity (HOT) and by time (NEW) as illustrated in FIG. 21, whichshould not be interpreted as limiting the present invention.

While the three card objects 1310, 1330 and 1350 are shown in FIG. 21 asdisplayed on the display 180, this is purely exemplary. Thus, the numberof displayed card objects may be changed. For instance, the card object1310 may be displayed alone or along with another card object on thedisplay 180.

Any of the card objects displayed on the display 180 may be exchangedwith another card object. Specifically, the card object 1330 or 1350 maybe exchanged with any other card object according to a control signalreceived from a local key or the remote controller 200, thereby allowingthe user to simply select an intended service. Herein, the card object1310 having the broadcast image 1315 may be kept displayed so that theuser can continue viewing the broadcast image 1315.

An application menu 1320 may be displayed in the application menu areadefined on a lower part of the display 180. The application menu 1320includes a plurality of application menu items, particularly preferredapplication menu items (Search and App Store) and optional applicationmenu items (DVR, Bluray, MAZON, and SNS) set by the user. The SNS menuitem may represent an application that can execute a plurality of SNSs.

With the setup object 1318 displayed on the display 180, the user mayenter the setup menu using the pointer 205 of the controller 200, whichshould not be interpreted as limiting the present invention. To enterthe setup menu, many other settings are possible. For instance, thesetup menu may be directly entered through input of a Setup key of theremote controller 200. With the setup object 1318 displayed on thedisplay 180, the setup menu may be directly entered through input of alocal key or through input of a directional key and/or an OK key of theremote controller 200.

Login information for a plurality of SNSs is stored in the setup menu(S1110).

Referring to FIG. 22, the user sets login information for a plurality ofSNSs such as Pacebook, Witter, TSN, and Myhome in the setup menu 1410,by way of example. Other SNSs including blogs and messengers are alsoavailable. The login information may include an ID and a password.

The user may enter an ID and a password for each SNS using local keys,letter keys of the remote controller 200, or a letter key objectdisplayed on the display 180.

Upon receipt of a save input for the login information after the logininformation is completely entered, the controller 170 controls saving ofthe login information in the memory 140.

FIG. 20 illustrates an example of data transmission and receptionbetween the image display apparatus 100 and social network servers1210-1 to 1210-n that provide a plurality of SNSs. In accordance with anembodiment of the present invention, the image display apparatus 100 mayaccess the plurality of SNSs and display the SNSs or other users orelectronic devices subscribed to the SNSs on the display 180. Herein,the term ‘other electronic devices’ may refer to electronic devices(e.g. mobile phones, PCs, TVs, etc.) registered with the SNSs.

If an SNS is not accessible using login information set for the SNS, thecontroller 170 may display an object notifying that the logininformation is not valid on the display 180.

Since login information is preliminarily stored for a plurality of SNSsas described above, the user may directly access the SNSs using thestored login information without a login procedure.

After the login information is stored, an image is displayed on thedisplay 180 (S1115). Specifically, once the setup menu is exited, thecontroller 170 controls display of an image on at least a part of thedisplay 180. The image may be a broadcast image or an external inputimage.

Upon completion of saving the login information in the setup menu 1410of FIG. 22 triggered by selecting the setup object 1318 of FIG. 21, theimage display apparatus 100 may return to the screen of FIG. 21 or 23 inwhich the broadcast image 1315 is displayed on a part of the display180.

FIG. 26 illustrates an exemplary broadcast image 1810 fullscreened onthe display 180. When the setup menu 1410 is exited, the broadcast image1810 may be displayed alone on the display 180, compared to the screenillustrated in FIG. 21 or 23.

It is determined whether an application menu display input has beenreceived (S1120). Upon receipt of the application menu display input, anapplication menu is displayed on at least a part of the display 180(S1125).

More specifically, the controller 180 monitors receipt of theapplication menu display input according to a control signal receivedfrom a local key or the remote controller 200. Upon receipt of theapplication menu display input, the controller 180 controls display ofthe application menu on at least a part of the display 180.

The application menu display input may be created using an additionalmenu displayed on the display 180, using a local key set as a hot key,or a hot key provided in the remote controller 200. The hot keyfunctions to directly open an application menu.

FIG. 27 illustrates an example in which an application menu 1920 isdisplayed along with an already displayed broadcast image 1910. Uponreceipt of the application menu display input while the broadcast image1810 is being displayed as illustrated in FIG. 26, the application menu1920 is additionally displayed on the lower part of the display 180 asillustrated in FIG. 27.

Unlike the screen configuration illustrated in FIG. 27, the screenillustrated in FIG. 21 or FIG. 23 is configured so as to include theapplication menu 1320. Therefore, when the image display apparatus 100is powered on or a local key or the Home key of the remote controller ismanipulated, the application menu 1320 may be displayed.

It is determined whether an SNS selection input has been received(S1130). Upon receipt of the SNS selection input, the SNS applicationmenu item is selected in the application menu (S1135). Subsequently, aplurality of social network servers are accessed based on the storedlogin information (S1140) and objects representing other users orelectronic devices subscribed to the plurality of SNSs are displayed onat least a part of the display 180 (S1145).

Specifically, the controller 170 determines whether an application menuitem representing SNS has been selected in the application menuaccording to a control signal received from a local key or the remotecontroller 200. Upon selection of the SNS application menu item, thecontroller 170 controls execution of the SNSs. That is, the controller170 controls access to a plurality of social network servers using thestored login information and controls display of objects representingother users or electronic devices subscribed to the plurality of SNSs onat least a part of the display 180.

FIG. 23 illustrates exemplary selection of an application menu item 1326representing SNS in the application menu 1320 using the pointer 205 ofthe remote controller 200. The selection of the SNS application menuitem 1326 triggers execution of a plurality of SNSs.

FIG. 24 illustrates exemplary display of a card object 1610 named TOTALSNS, representing a plurality of SNSs on the display 180, upon executionof the SNSs. It is noted that the APP STORE card object 1350representing an application list has been replaced with the TOTAL SNScard object 1610 on the display 180.

The TOTAL SNS card object 1610 contains objects representing other usersor electronic devices subscribed to the plurality of SNSs. Each of theseobjects may include an avatar, an image, an icon, or text indicating aname, which represents a user or electronic device. The objects may besorted by SNS. The term used herein ‘other electronic devices’ may referto electronic devices registered with the plurality of SNSs, such asmobile phones, PCs, TVs, etc.

In FIG. 24, the objects are sorted from a first SNS to a fourth SNS.Specifically, objects 1620 represent other users or electronic devicessubscribed to the first SNS, objects 1630 represents other users orelectronic devices subscribed to the second SNS, objects 1640 representother users or electronic devices subscribed to the third SNS, andobjects 1650 represent other users or electronic devices subscribed tothe fourth SNS. Meanwhile, the objects may be sorted such that logged-inusers are distinguished from logged-out users in the card object 1610.Also, the objects may be sorted according to user-set groups (e.g.friend, family, company, etc.)

In this manner, a plurality of SNSs are displayed on at least a part ofthe display 180, thereby allowing the user to easily identify otherusers or electronic devices subscribed to each SNS in the embodiment ofthe present invention. Accordingly, user convenience is increased.

As stated before with reference to FIG. 22, login information necessaryto access the first to fourth SNSs may be stored in advance.

FIG. 28 illustrates an exemplary object screen 2010 containing objectsrepresenting other users or electronic devices subscribed to a pluralityof SNSs, displayed on the display 180. Each of the objects may includean avatar, an image, an icon, or text, which represents a user orelectronic device. The objects may be sorted by SNS or from logged-inusers to logged-out users. The term used herein ‘other electronicdevices’ may refer to electronic devices such as mobile phones, PCs,TVs, etc. registered with the SNSs.

In FIG. 28, objects 2020 and objects 2030 are arranged in differentrows. The objects 2020 represent other users or electronic deviceslogged-in to the first SNS and the objects 2030 represent other users orelectronic devices logged in to the second SNS. Objects 2040representing other users or electronic devices logged out from the firstor second SNS are arranged in a row. To distinguish the objects 2020 and2030 representing the logged-in users from the object 2040 representingthe logged-out users, the objects 2040 may be displayed differently fromthe objects 2020 and 2030, in terms of at least one of color,brightness, contrast or outline thickness. Therefore, the user canreadily distinguish the logged-in users from the logged-out users.

Because the object screen 2010 illustrated in FIG. 28 is larger than thecard object 1610 illustrated in FIG. 24, the object screen 2010 maydisplay more objects than the card object 1610. Hence, the user can moreeasily identify other users of the SNSs.

It is also possible to continue to display the application menu 1920 inthe lower part of the display 180 along with the objects 2020, 2030 and2040 representing other users or electronic devices of the SNSs, asillustrated in FIG. 28.

On the other hand, FIG. 29 illustrates an example of displaying anobject screen 2110 alone without the application menu 1920. Referring toFIG. 29, in addition to objects 2120, 2130 and 2140 representing otherusers or electronic devices logged-in to the first and second SNSs,objects 2140 representing other users or electronic devices logged-in toa third SNS are arranged in a row. Thus the objects 2120, 2130 and 2140are distinguished from one another on a row basis. Objects 2150representing other users or electronic devices logged-out from thefirst, second and third SNSs are arranged in a row. Therefore, the usercan readily tell the logged-in users from the logged-out users.

The screen configuration of FIG. 30 is the same as the screenconfiguration of FIG. 29 in that an object screen 2210 is displayedalone on the display 180 without an application menu, and different fromthe latter in that each object further includes an icon that identifiesan SNS. Hence, the same icon represents the same SNS and different iconsrepresent different SNSs.

Referring to FIG. 30, each of objects 2220 representing other users orelectronic devices logged-in to the first SNS may include an icon 2225indicating Pacebook besides an avatar, an image or text (member 1).Thus, the user can identify the SNSs of other users or electronicdevices by such icons.
